A computer simulation of high velocity air flow around the Space Shuttle during re-entry A simulation of the Hyper-X scramjet vehicle in operation at Mach-7. The fundamental basis of almost all CFD problems is the Navier–Stokes equations, which define many single-phase (gas or liquid, but not both) fluid flows.
Most models use meshes which are either structured (Cartesian or curvilinear grids) or unstructured (triangular, tetrahedral, etc.). Gerris is quite different on this respect: it implements a deal between structured and unstructured meshes by using a tree data structure, [a] allowing to refine locally (and dynamically) the (finite-volume) description of the pressure and velocity fields.
SAFE AIR II (Italy) – The simulation of air pollution from emissions II (SAFE AIR II) was developed at the Department of Physics, University of Genoa, Italy to simulate the dispersion of air pollutants above complex terrain at local and regional scales. It can handle point, line, area and volume sources and continuous plumes as well as puffs.

Vortex (software) - a complete simulation platform featuring a realtime physics engine for rigid body dynamics, an image generator, desktop tools (Editor and Player) and more. Also available as Vortex ...
Atmospheric dispersion modeling is the mathematical simulation of how air pollutants disperse in the ambient atmosphere.It is performed with computer programs that include algorithms to solve the mathematical equations that govern the pollutant dispersion.
FlightGear Flight Simulator (often shortened to FlightGear or FGFS) is a free, open source multi-platform flight simulator developed by the FlightGear project since 1997. [ 4 ] David Murr started this project on April 8, 1996.

SPH simulation: pressure distribution of a dam-break flow using standard SPH formulation SPH simulation: pressure distribution of a dam-break flow using standard δ-SPH formulation. In Antuono et al. [61] a correction to the diffusive term of Molteni [56] was proposed to remove some inconsistencies close to the free-surface.
